AST_GRID
-
Draw a set of labelled coordinate axes
- Description:
- This routine draws a complete annotated set of
coordinate axes for a Plot with (optionally) a coordinate grid
superimposed. Details of the axes and grid can be controlled by
setting values for the various attributes defined by the Plot
class (q.v.).
- Invocation:
- CALL AST_GRID( THIS, STATUS )
- Arguments:
-
THIS = INTEGER (Given)
-
Pointer to the Plot.
-
STATUS = INTEGER (Given and Returned)
-
The global status.
- Notes:
- If the supplied Plot is a Plot3D, the axes will be annotated
using three 2-dimensional Plots, one for each 2D plane in the 3D
current coordinate system. The plots will be "pasted" onto 3 faces
of the cuboid graphics volume specified when the Plot3D was
constructed. The faces to be used can be controlled by the "RootCorner"
attribute.
- An error results if either the current Frame or the base Frame
of the Plot is not 2-dimensional or (for a Plot3D) 3-dimensional.
- An error also results if the transformation between the base
and current Frames of the Plot is not defined in either
direction (i.e. the Plot's TranForward or TranInverse attribute
is zero).
